How Do I Clear The Credentials In AWS Configure?

just remove ~/.aws/credentials along with ~/.aws/config

EDIT: Note path references user home directory and specific to each user in system.

Do not delete the files if you have multiple profiles created as all will be lost if you delete these files! unless thats what you want :)

Go to each of the file -

 - ~/.aws/credentials
 - ~/.aws/config

and remove just the part profiles you want to delete. Eg.

~/.aws/credentials

[default]
aws_access_key_id=yourAccessKeyId
aws_secret_access_key=yourSecretAccessKey

[user2]
aws_access_key_id=yourAccessKeyId
aws_secret_access_key=yourSecretAccessKey

and

~/.aws/config

[default]
region=us-west-2
output=json

[profile user2]
region=us-east-1
output=text

Just delete entries corresponding to user2 profile if thats what you want. And you should also give a profile name to profile you configure -

aws configure --profile user2

Else it will just be [default]
